type of gas saving device described in the patent to Lampert 1,192,435,issued uly 25, 1916, which patent provides for an .article tc beinserted between a carburetor and the intake ports of an engine, thedevice including a metalplate meliiber having a coiled spring conemounted over an opening in the plate member, and having itsbase coilliked to the plate member, the remainder of the cone being unattachedandfree to vibrate.

in the Lampert device, the plate is of solid material; has the generalcontour of a gasket; and is used between adjacent danges of pipe ends.The metal wall of the opening in the Lampert device is provided with anan nular groove to receive and hold, by the eXf pansive spring action,the largest or base;

coil of the spring cone.

The general object of the present invention is to improve on the Lamperttype of device, and at the same time, retain the advantageous featuresof the 'freely vibratile spring cone. i

One of the featuresof the invention relates to the improved means for sosecuring the base coil of Ythe spring wire to the supporting plate thatthe coil cannot be looscned or separated accidently from the supportingplate, due to the vibrations of the spring or the jolting or vibrationof the en me.

nother feature is the combination of thespiral s ring with the standardasbestos copper gas et', supplemented and modified by rlihis designmakes it possible to insert the plate or gasket and springsidewise intoposition between adjacent pipe lends without necessitating the wideseparation-of the connection, it being merely necessary to loosen theconnection sulliciently wide to insert the .thicknessoi the plate orgasket. After such insertion, the spring cone is then free to assumeitsnorma conical shape, and 'to serve in breaking up the incoming chargentthe uel mixture. This feature is particularlyimportant because ot' theease by which the device may be installed. By using an as bestes coppergasket of ordinary thichess and having the cross-sectional'diameter o3the material of the spring-'no greater than the thickness of the gasket,the device may readily be inserted in any engine intake line withoutrequiring modification of the engine parte.

lhe device or the present invention may ,be inserted at any connectionbetween the carburetor and the inlet ports. Satisfactory locations havebeen at 'the engine and at the carbureter ends of the intake manifold.The apex of the cone may extend in either direction, accordi toconvenience, provided it does not inter ere with the engine parts.

The above and other features and advantages of the device of theinvention will loe described and claimed in the following speciicationand claims, and illustrated in the accompanying drawing, in which:

Fig.` 1 represents a sectional view through one 'form of the device,showing theconical spring having its lower and lar est coil held betweenopposite metal faceso an asbestos copper gasket, the` intermediateasbestos portion being spaced back from the central opening to providespace for the reception of the spring;

Fig. l.2 shows a sectional view through a form of the device, includingan asbestos cop r gasket, in which an annular' ring hol s the lower andlargest coil of the spring in its position adjacent the wall of theopening through the gasket. In this form, the ring is a Separate memberand extends from one face ofthe asket through the opening and alongsideo? the opposite gasket face;

' plura ityof e elets, struck up Fi 6 represents a sectional view of amodified form of the combined asbestos copper gasket and spring, inwhich one face ofthe metal portion of the asbestos copper gal-skeinprojectscentrally and then axially t ough the openin and is recurvedabout the largest coil of t e spring and alongside of the opposite faceof the gasket;

Fig. 7 represents, in section, a modification of the for'm illustratedin Fig. 6, the

sprin retaining means being formed of a from the material of one ace;and f Fig. 8 represents a. top plan view of the asbestos copper gasket,shown inv Fig. 7, illustrating one of the eyelets projecting centrallyprior to being recurved about the largest coil of the spring member.

Referring in detail to the various figures of the drawings, likenumerals. refer to like parts in the different figures. j

1 is a spiral spring member formed in the shape of a cone, and sodesigned that it may be compressed to a plane having the thickne' of across-section of the material of the Wire, as illustrated in Fig. 4. Theapex of the cone is indicated at 1, The base of the cone is formed bythe largest coil or turn of the spring wire and is indicated at 1*. 2represents a gasket member or plate upon which the sprin 1 is mounted,and which serves to hold tie spring in its operative position wheninstalled in the intake line of aninternal combustion engine. 3 is acentral opening in the member 2, and 4 indicates end slots or openingsfor the reception oit fastening bolts or studs by'whichthe member 2 andits adjacent pipe connections are 4secured together. The spring 1 isheld in its mounted position with the axis of the cone in line with theaxial center of the o ening 3 and accordingly, the largest coil lb isheld adjacent to the wall of the opening 3, or actually in the sameplane with the wall of the opening. v

The invention provides several different speciiic constructions forsecurely holding the coil 1" in its position about the opening 3. In thesectional views of the drawing, the upper face of the gasket member isindicated at 2a and the lower face is indicated at 2b, and the asbestosintermediate portion of the gasket is indicated at 2. In the formillustrat/ed in Fig. 1, the asbestos portion 2 is cut back away from thecentral opening, thus providing an annular space between the faces 2 and2", as indicated at 5. The largest coil of the conical spring 1 is shownheld in of the inslaan means is thus formed as a ring having an annulargroove, the side walls of which enclose the largest coil 1' of thespring cone, and also 'that portion of the gasket metal faces 2a and 2bnext adjacent the lcentral opening 3. In both Figs. 2 and 3, anopening'7 will be seen, through which the upwardly extending springprojects. The opening 7 is preferably elongated in order to preventundue distortion of the curvature of the spiral spring. It is desirablealso that the opening 7 extend through the thickness of the member 6,suiicientlydeeply so 'that the coil of the spring projecting through theopeningV may be compressed to the plane of the gasket, as in Fig. 4.

ln the modification illustrated in Fig. 6, the retaining element 6 isformed by an eX- tension of the under face of the copper portion of thegasket, which will be seen as eX- tending centrally, thence through theopening, and thence alongside ot' the opposite face 2a. This arrangementis substantially the same in eii'ect as the form illustrated in Fig. 2,except that the part 6 is formed as a continuation of one gasket faceinstead of being a separate member, as in 2.

vIn the modification illustrated in Figs. 7 and 8, the under face of thecopper portion asket is extended inwardly to forni a plura ity ofeyelets 8 adapted to be curved upwardly through the opening 3 and thencealongside of the .opposite face of the gasket. This arrangement issubstantially similar to the arrangement illustrated in Fig. 6, ex-

cept that the eyelets are formed separatelyv instead of as onecontinuous portion` as illustrated in Fig. 6. In Fig. 8, the length ot'one eyelet member is shown as fully extended centrally, and prior to therecurving of it into the eyelet shape.

In the arrangement shown in Fig. 1, the outward spring expansive actionof the larger coil 1b serves to hold it in the annular space betwen theopposite faces of the copper portion of the gasket. In the other viewsof the drawing, it is intended that the end of the'larger coil of thespring cone be inserted into the opening 7 and the coil and gasketrotated with respect to each other, so as to thread the largest coil 1binto and around through the space provided by the fastening member 6,the side faces 2a and 2b of the gasket and the asbestos material 2c. lnthe lll) form shown in 7 and 8", the eyeletv members may be bent up andrecurved around the largest coil 1b of the wire, ortho end of thelargest coil may be threaded through the plurality of eyelets insubstantially the same manner as provided for in Figs. 2, 3, 4. and 6.

For the insertion of the combined spring and gasket into position in aninternal combustion engine, the invention contemplates vthe use of anynecessary device. such as a pair of pliers, by which the spring may becompressed to the thickness of the material of the gasket by the samemovement and by the Same position of the implement which the operatoruses in holding the gasket. If the place of installation beI readilyaccessible, and the spring readily compressible, the operator may usehis lingers in compressing the spring and' slipping the device sidewise,ordedgewise, in between the adjacent pipe en s.

The curvature of the spirals of the spring should be so arranged'that aline drawn through the material of the spring at any point and parallelto the axis of the cone will not pass through the material of the nextadjacent turn or coil of the spring, or any other portion of the spring.This description is presented as one way of stating that the conicalspring ma be compressed to a given plane without istorting any of theturns or coils of the spring in order to assume'the plane position.
